Types discussion:
In 1991 cholera was reported for the first time in this century in South America, starting in Peru. The outbreaks quickly grew to epidemic proportions and spread to other South American and Central American countries, and into Mexico. 1,099,882 cases and 10,453 deaths were reported in the Western Hemisphere between January 1991 and July 1995.
Although the South American strain of V. cholerae O1 has been isolated from Gulf Coast waters, presumably transmitted by ships off-loading contaminated ballast water, no cases of cholera have been attributed to fish or shellfish harvested from U.S. waters. However, over 100 cases of cholera caused by the South American strain have been reported in the United States. These cases were travelers returning from South America, or were associated with illegally smuggled, temperature-abused crustaceans from South America.
In the Autumn of 1993, a new strain, a non-O1 never before identified, was implicated in outbreaks of cholera in Bangladesh and India. The organism, V. cholerae serogroup O139 (Bengal), causes characteristic severe cholera symptoms. Previous illness with V. cholerae O1 does not confer immunity and the disease is now endemic. In the U.S., V. cholerae O139 has been implicated in one case, a traveller returning from India. The strain has not been reported in U.S. waters or shellfish.
